Abstract
Official abstract text for this publication.
A quinone derivative is represented by general formula (1). In general formula (1), at least one of R 1 -R 3 and at least one of R 4 -R 6 each represent, independently of one another, an alkyl group having 4 to 10 carbon atoms or an alkyl group having 2 to 5 carbon atoms that has an aryl group having 6 to 14 carbon atoms. All other of R 1 -R 3 and all other of R 4 -R 6 each represent, independently of one another, an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 14 carbon atoms, or a cycloalkyl group having 3 to 10 carbon atoms.
First claim
Opening claim text (preview).
What is claimed is: 1. A quinone derivative that is represented by any one of chemical formulae (1-1), (1-3), and (1-6) 2. An electrophotographic photosensitive member comprising a conductive substrate and a photosensitive layer, wherein the photosensitive layer contains a charge generating material, a hole transport material, a binder resin, and the quinone derivative according to claim 1 . 3. The electrophotographic photosensitive member according to claim 2 , wherein the charge generating material contains an X-form metal-free phthalocyanine or a Y-form titanyl phthalocyanine. 4. The electrophotographic photosensitive member according to claim 2 , wherein the hole transport material contains a compound represented by general formula (2) shown below: where, in the general formula (2), R 21 , R 22 , R 23 , R 24 , R 25 , and R 26 each represent, independently of one another, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms, r, s, v, and w each represent, independently of one another, an integer of at least 0 and no greater than 5, and t and u each represent, independently of one another, an integer of at least 0 and no greater than 4. 5. The electrophotographic photosensitive member according to claim 2 , wherein the photosensitive layer is a single-layer photosensitive layer.
